And both a setup so it's as close as it can get without hitting the sensor arm

Sounds exactly like the problem I'm having. I tried a stronger magnet, changed where it passes the sensor arm and it still doesn't light up green with I test it. The cadence works fine though, both when testing and when riding normally. I think the sensor has had its time and needs replacing which is annoying as they are $50 to replace.

Did you have problems then with the HRM readings?When sensor stopped picking up the magnet thats when all of a sudden the HRM stopped working..I also may have gone out on a ride without the magnet on my training set and It also stuffed up the HRM readings if I recall

I've got the polar strap in the mail (about $20) and will report back on progress...

Oz, did you find the Garmin transmitter stays on the Polar strap? I like you bought a Polar strap and the Garmin transmitter pops off quite easily. Any tips?

Burr the button a little with some pliers, or use a small pointy probe to bend out the catch mechanism... If that failed then electrical tape it on...

Thanks for the Dr, my Garmin strap is just about worn out from too many washes. I was doing a club ITT on Sunday and after 8kms my HR was saying 75bpm. I was gasping for air and it should of had a 1 in front of that .
